Improving pair and tuple, revision 1

by Daniel Krügler

Excerpt:

Changes since N3680:

• During a straw-pool vote there was a small majority (4:3) in favour for keeping the two-signatures approach, so this presentation form was used in this revision.
• The original example has been improved.
• The missing application of the declaration pattern to the allocator_arg_t constructors has been fixed.
• Consequent usage of the more precise is_convertible trait instead of the somewhat vague is implicitly convertible description.
